BUTTON.

Specification of Letters Patent.

Patented Oct. *7, 1919.

Application filed December 6, 1918. Serial No. 265,624.

To all whom it may concern:

Be it known that I, RUDOLPH R. SIEBERT, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in Buttons, ofwhich the following is a specification.

The present invention relates to buttons, more particularly to the typein which the button body has a shank embedded therein for the purpose ofconnecting such shank with the body. An object of this invention is toprovide an improvement on the shank shown in the application of Lloyd A.Angle, filed Aug. 22, 1918, Serial No. 251,035. A further object of thisinvention is to provide an improved shank which may be made from wirestock with'an anchoring portion so formed as to permit the shank to bedriven into the button body to obtain a firm anchorage therein, while atthe same time preventing the rotation of the shank in the body To theseand other ends the invention consists of certain parts and combinationsof parts, all of which will'behereinafter described and moreparticularly pointed out in the appended claims.

In the drawing Figure 1 is an edge view of the shank constructed inaccordance with the present invention;

Fig. 2 is a side view of the same shank;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a section on the line 44.-, Fig. 2; Fig. 5 is a section on theline 55, Fig. 2,

Fig. 6 is a detail view of the rear face of the button body showin thecircular opening formed therein be ore the shank is driven into thebody.

Fig. 7 is an enlarged sectional View of the button body showing a shankin position on the body; and

Figs. 8 and 9 are two. views of the button complete.

In the before mentioned application of Lloyd A. Angle, filed August 22,1918, Serial No. 251,035, a button is provided in which the bodyconsists of resilient material such as vulcanized fiber, or leatherboard, and into this body a shank is forced; the body in the firstinstance being provided with an opening in its rear face and the shankhaving an anchoring portion formed with an enlargement of a greatercross-section than the opening of the body, the anchoring portion of theshank being forced into the opening while the button body is in a drystate and the material of the button body crowding behind the shoulderformed on the shank by the enlargement. In the before mentionedapplication the shank is illustrated as being formed from a solid pieceof metal which must be cut or stamped to give it the desired shape,whereas according to this in vention, the shank is formed from wirestock and, in the illustrated construction, this stock is bent midwaybetween its ends to provide aneye portion 1 at the bend, and anchoringportion at the" ends which are brought into abutment, the opposedabutting faces 2 of the anchoring portion, preferably being flattenedasillustrated in Fig. 5 of the drawing. The outer faces of the anchoringportion of the shank at the ends of the stock are provided withconverging surfaces 3, and above these converging surfaces shoulders 4are formed, these converging surfaces as well as the shoulders Adefining the enlargement at the end of the anchoring portion of theshank. Above the shoulder 4c the anchoring portion has two convergingouter faces 5 which merge into the outer faces of the eye 1. Preferablythese converging faces and the shoulders A are formed by reducing thewire stock transversely by compression.

The button body 6, as in the Angle application No. 251,035 hereinbeforereferred to, is made of resilient material and is bored in its rear faceto provide a pocket 7 Into this pocket, the anchoring portion of theshank is driven until the parts assume the positions indicated in Fig.7. The diameter of the opening 7 is less than the greatest diameter ofthe enlargement of the anchoring portion of the shank. When the enlargement is driven into the button body, the material expands above theshoulders 4 and is again compressed by the converging faces 5 of theanchoring portion, the shank being driven into the button to thoseportions of the converging faces which are separated apart a distance atleast as great as the greatest diameter of the enlarged portion so thatthe opening in the rear face of the button body will be completelyfilled by the, base of the anchoring portion, thus preventing anymovement the shankin the button body. The cross-sectional form of thebutton shank is non-circular and this prevents any rotation of the shankin the button body.

From the foregoing it will be seen that there has been provided a shankwhich may be made fromcwire stockand driven into a button body made ofresilient material to form a firm connection between the shank and thebutton body, preventing any rotation of the shank in the button body, orin fact any movement whatsoever of the shank in the button'body. V c

What I claim'as my invention and desire to secure by Letters Patentvis1- f 1. A button comprisingga button body and a button shank includingan eye and an anchoring portion, both formed from a single piece ofwirestock bent between its ends, the eye being arranged atthe bend, theanchoring portion being formed by portions near the ends, the opposedfaces near the ends lying in abutment, and the anchoring portionhavingouter faces formed with converging portions which extend tolthe ex tremeends of the stock. I

2. A button. comprising a button body, and a button shank includinganeye and an anchoring portion, both' formed from a single piece of wirestock bent between its ends, the eye being arrangedat the bend, theanchoring portion being formed by portions near the ends, an anchoringportion having outer faces formed with converging portions which extendto the extreme ends of the stock, and each outer face being providedWith'a shoulder above its converging portion. I

3. A button comprising a button body,

and a button shank including an eye and an anchoring portion, bothformed from a wlre stock bent between its single piece of ends, the eye.being arranged at the bend, the anchoring portion being formed byportions near the, ends, the anchoring portion having outervfaces formedwith converging portions which extend to the extreme ends of the stockand the outer faces being provided. with shoulders above the convergingportions and also with faces above said shoulders converging withrelationito each other.

4. A button comprising a button body and a button shank formed fromwire'stockj bent upon itself to: provide an eye, an anchoring-portion,the eye being formed at the bend, the anchoring portion being formed byportions near the two'ends. of the stock beyond the eye,- the opposedfaces 'ofthe stock, in the anchoring portion being flattened and lyingin abutment, and the outermost faces of'said anchoringfportion 7 havingconverging portions extending to the extreme of the stock and being.provided with shoulders above saidconverging portions. 4
